1. Problem Description

We are given a graph of a function and asked to find the intervals where the function is increasing, decreasing, or constant, as well as the domain and range of the function.

2. Solution Steps

* Increasing Interval: The function is increasing when the y-value increases as the x-value increases. From the graph, this occurs from x=2x = 2 to x=5x = 5. At x=5x=5 the function has a hole, so the interval is (2,5)(2, 5).
* Decreasing Interval: The function is decreasing when the y-value decreases as the x-value increases. From the graph, this occurs from x=6x = -6 to x=3x = -3. Since 6-6 is a closed circle, the interval includes 6-6. Therefore, the interval is [6,3)[-6, -3).
* Constant Interval: The function is constant when the y-value remains the same as the x-value increases. From the graph, this occurs from x=3x = -3 to x=2x = 2. Therefore, the interval is [3,2][-3, 2].
* Domain: The domain is the set of all possible x-values for the function. From the graph, the function is defined from x=6x = -6 to x=5x = 5. Since 6-6 is a closed circle and 55 is an open circle (hole), the domain is [6,5)[-6, 5).
* Range: The range is the set of all possible y-values for the function. The minimum y-value is 2-2, and the maximum y-value approaches

1. Therefore, the range is $[-2, 1)$.

3. Final Answer

* Increasing: (2,5)(2, 5)
* Decreasing: [6,3)[-6, -3)
* Constant: [3,2][-3, 2]
* Domain: [6,5)[-6, 5)
* Range: [2,1)[-2, 1)
